RE: [PHP] Changed variabele

Well, this is something you should play with just like I am playing with it right now.. (you might be lucky to have found me here awake:-))) What you need is to write a function that will generate a link for you. But this is sort of complicated, if there not too many staff you could then only write it like this: $This_Page="$SCRIPT_NAME?"; $Get_Vars = $HTTP_GET_VARS; function LinkGenerator($var, $val) { Global Get_Vars; for(reset($Get_Vars); $key=key($Get_Vars); next($Get_Vars)) { if($key==$var) Continue; else $this = $Get_Vars[$key]; $link .= "$key=$this&"; } return "$link$var=$val"; } ?> <P>Then you can echo it here: <P><?=$This_Page.LinkGenerator('link', 'contact')?> <P><?=$This_Page.LinkGenerator('link', 'home')?> <P>and this would replace only the 'link' with what you give to him, Try to write something in your URL.. Hey, I just wrote a whole code for you! And I will use for my own! Thanks for your question, you make me do the things I was always lazy to. :-)) The code is not perfect, I will do something to support more then 1 change in the link. But this is also pretty helpful.

When I click on them, the $link has been changed so if it reads index.php3 again, I have to look if the $link has been changed. And then I can use the switch I guess... But, another problem: if I click on a link at index.php3 (for example index.php3?language=dutch), all other variables will be empty when it reloads! How is that possible?

The included pages are becoming the part of the script, so you can use everything available in every text you include. Ithink the expample you gave would work, but I am not sure I understood you.. if I want to check whether someone is asking for home link or contact in a URL like http://site.com/page=contact: then: if($page=='home') $link='/index.html'; elseif($page=='contact') $link='/contact.html'; else $link='Unknown link, sorry'; would do the simple trick.

So, if I use '#include bla2.php3' can I use is in the file bla2.php3 ? - How can I check if a variable has changed? I made links in my document like : index.php3?link=home and index.php3?link=contact In index.php3 I want to check if a variable has changed, so if a link is clicked. Can I do it by this: if ($link) { switch ($link) { case "home": { echo "<HTML>" } case "contact": { echo "contact" } } $link=""; } ?
